if you use usb keyboard (or ps2 to usb converter with ps2 keyboard), 
does it work?

like i said before, i think, the problem is that atkbd(4) does not deal 
with "polled" mode properly. kbdmux(4) never sees input from atkbd(4) 
because (imo) atkbd(4) interrupt handler is never called. the atkbd(4) 
patch i posted awhile ago has a regression, i.e. atkbd(4) produces 
duplicate characters in ddb(4), midboot, etc. *without* kbdmux(4). 
patched atkbd(4) with kbdmux(4) works fine.

i'm actually a bit puzzled why atkbd(4) works without kbdmux(4) in 
ddb(4), midboot,e etc. obviously i need to spend some quality time with 
the debugger :) i hope to get to it, eventually :) sorry for the delay.

thanks,
